    • To curl or not to curl : wind tunnel investigation of spinnaker performance 
      Communication avec acte
      AUBIN, Nicolas; AUGIER, Benoit; DEPARDAY, Julien; SACHER, Matthieu (Ecole Navale, 2017)
      This work presents a wind tunnel experimental study of the effect of curling on the spinnaker aerodynamic performance. Four spinnakers combining two different panellings and sail materials are tested at different wind ...
    • Experimental validation of unsteady models for wind / sails / rigging fluid structure interaction 
      Communication avec acte
      AUGIER, Benoit; DURAND, Mathieu; ccBOT, Patrick; ccHAUVILLE, Frederic (Royal Institution of Naval Architects, 2010)
      The aim of this paper is to present the work of experimental validation elements of the aero elastic and unsteady model ARAVANTI. Numerical and Experimental results comparison is made on the rigging and sails of a J80 sail ...
    • Wind-tunnel pressure measurements on model-scale rigid downwind sails 
      Communication avec acte
      VIOLA, Ignazio Maria; FLAY, Richard G.J.; BRETT, Jean-Sébastien; ccBOT, Patrick (Ecole Navale, 2013)
      This paper describes an experiment that was carried out in the Twisted Flow Wind Tunnel at The University of Auckland to measure a detailed set of pressure distributions on a rigid 1/15th scale model of a modern asymmetric ...
    • Experimental and numerical trimming optimizations for a mainsail in upwind conditions 
      Communication avec acte
      SACHER, Matthieu; DUVIGNEAU, Régis; LE MAITRE, Olivier; AUBIN, Nicolas; DURAND, Mathieu; ccHAUVILLE, Frederic (2016)
      This paper investigates the use of meta-models for optimizing sails trimming. A Gaussian process is used to robustly approximate the dependence of the performance with the trimming parameters to be optimized. The Gaussian ...
    • Optimisation de la loi de calage d’un propulseur cycloïdal 
      Communication avec acte
      LECUYER-LE BRIS, Romain; DENISET, François; FASSE, Guillaume; ccHAUVILLE, Frederic (2018)
      Les propulseurs cycloïdaux sont caractérisés par la rotation de plusieurs pales autour d’un axe vertical, associée à un mouvement de chaque pale autour de son axe propre. L’objet de cet article concerne l’étude des lois ...
    • How to be the best at sail pumping? 
      Communication avec acte
      AUBIN, Nicolas; DHOME, Ulisse; AUGIER, Benoit; ccBOT, Patrick; ccHAUVILLE, Frederic (2016)
      Pumping or flicking1 is often used by sailors to get extra propulsion while sailing (subject to restrictions by the racing rules2). Common unsteady sailing situations, due to crew action (e.g. manoeuver like gybing3) or ...
    • Modal Analysis of Pressures on a Full-Scale Spinnaker 
      Communication avec acte
      DEPARDAY, Julien; AUGIER, Benoit; RABAUD, Marc; MOTTA, Dario; LE PELLEY, David; ccBOT, Patrick; ccHAUVILLE, Frederic (2016)
      While sailing offwind, the trimmer typically adjusts the downwind sail "on the verge of luffing", letting occasionally the luff of the sail flapping. Due to the unsteadiness of the spinnaker itself, maintaining the luff ...
